Description

The present invention relates to a self-teller for liquids with several coin inlet points, in which an operating circuit is closed by inserting a coin and a pump is in operation for so long is held until the circuit is automatically triggered '.

According to the invention, a single lever is sufficient for the following three operations, namely for setting the slot corresponding to the coin in front of the Throwing groove, also for setting the organ that regulates the inflow of liquid, and also for setting the drainage of the liquid pumped into the collecting tanks by a single rotatable lever.

The invention is shown in the accompanying drawing.

Fig. Ι shows the lever H for moving a rail S located in front of the insertion openings, which rail also has a slot.

Fig. 2 shows the rail S in side view in connection with the indicated insertion groove, the tube E with the rotary tap D for transferring the liquid through tubes into the containers B ¹ , B ² , B ³ , as well as the drainage tube with the valves V ¹ , V ^% , V ^s , which are operated from the rotary tap by means of a lever system H *, H ^3. At the same time, the overflow pipe is shown in this figure. Fig. 4 shows the top view of Fig. 2. ·

Fig. 5 shows the pipe with rotary tap in cross section, while

Fig. 5 a the tube with the rotary tap in a longitudinal section shows.

Fig. 6 shows a section through the gasoline container B with overflow pipe and indicated insertion groove, while

Fig. 7 shows a longitudinal section through fig.

The apparatus of the invention shows the appearance of conventional gas stations. In the front wall there are insertion openings α, b and c (Fig. 1 and 2) for various coins, e.g. B. 1, 3 and 5 MJt, arranged one above the other, with a slot behind each opening. A lever H ¹ (Fig. 1, 2 and 4) is connected to a rail S (Fig. 2, 3 and 4) in such a way that the same can be moved vertically. There is also a slot in the latter.

The petrol taker now sets the lever H ¹ to the slot he wants, e.g. B. a, a. As a result, the slot in the rail S comes behind the opening a, and the same is connected to the slot located behind it. The coin can be inserted and rolls downwards, whereupon it completes a circuit at the end of the groove. This activates a pump and pumps gasoline from the storage tank into the measuring container B ¹ , J5 ² or B ^s belonging to the coin slot used. The liquid

must pass the rotary tap D (Fig. 2, 4 and 5). This rotary tap has the same number of outflow openings 0 \ O ² , O ³ as the throw-in openings a, b, c, and accordingly there are also measuring containers S ¹ , B ² , B ³ . The outflow openings O ¹ , O ² , O ^{s of} the rotary tap D are connected to the associated container B ¹ , B ² or B ³ by pipelines. The rotary valve E in the tap D (Fig. 5) is rotatably arranged with the lever H ^1. By moving the lever H ¹ up and down about the central axis of the tap D , the slide E is also rotated, and the opening 0 * in it is forcibly set to one of the openings O ¹ , O ² , O ³ , depending on the Lever H ^{1 is set} to a, b or c. For example, if the lever H ^{1 is} on a, O ^{4 is} connected to O ¹ and the gasoline flows to container B ¹ . In each measuring container B \ B ² , B ³ , a calibrated overflow pipe U (Fig. 6) for measuring the amount of gasoline is expediently arranged. These overflow pipes can be exchanged so that if the price of gasoline changes, the corresponding permanent monetary value can be adjusted. If one of the measuring containers is fully pumped, the remaining amount of gasoline flows through the overflow pipe into a common overflow line. In this line there is a flap F (Fig. 6 and 2) with a balance. There is a scale in each of the stacking grooves. These scales are all connected to flap F (Fig. 6). The weight of the column of liquid in the overflow pipe turns the flap F, whereby the scale carrying the coin is opened and the coin falls out. This interrupts the circuit again and the motor or pump is shut down. In order to take the petrol from the machine, the outer arm of the lever H ^{1 must be put} all the way down. Therefore, the claw K (Fig. 2) at the inner end of the lever JEi ¹ comes into engagement with the pin N of a lever H ² (Fig. 2), which is thereby rotated by p and pushes another lever H ³ to the left, whereby the valves F ¹ , V ² , V ^s in the drain pipes are opened. The petrol can flow out of the machine through the common drain line. If lever H ¹ is moved upwards again, lever H ² is also withdrawn, valves V ^s -, V ² , V ³ are closed, and the machine can be used again.

Claims (3)

Patent claims: i. Self-cashier for liquids with several insertion grooves, in which an operating circuit is closed by inserting money, characterized in that a lever (H ¹ ) can be rotated around the central axis of a rotary tap (D) which causes the supply to the operating material containers and which at the same time corresponds to the coin used Adjusts the inlet groove and connects the appropriate outlet opening (O ¹ , O ² , O ³ ) of the rotary tap with the petrol container (B ¹ , B ² or jB ³ ) that matches the coin inserted until the operating circuit is interrupted by overflow fluid , whereupon the drain valves (F ¹ , F ² , F ³ ) are opened by further turning this lever (H ¹ ). 2. Self cashier for liquids according to claim 1, characterized in that with the lever (H ¹ ) still one in front of the various coin slots (a, b, c) displaceable rail (S) is connected so that upon movement of the lever (H ¹ ) the slot is set behind the inlet groove corresponding to the coin in question. 3. Self cashier for liquids according to claim 1, characterized in that the opening of the shut-off valves by the lever (H ¹ ) takes place in such a way that this pushes against a bolt (N) of a second lever (H ² ) at the end of its rotary movement and through this one lever (H ³ ) rotates which is connected to levers leading to the drain valves (F ¹ , F ² , F ^3). 1 sheet of drawings
